The study found that patients with tumors showing higher overall blood vessel density had better survival, and a higher proportion of microvessels was associated with better outcomes.
The results are published in JAMA Network Open.
“Numerous blood vessels extend deep into tumors, yet their role in tumor biology is still relatively understudied,” explained corresponding author Shuji Ogino, MD, chief of the Program in Molecular Pathological Epidemiology in the Department of Pathology at Mass General Brigham.
